T46 Attended transfer recalls - Phillipk - 01-21-2016 05:06 AM


We have two T46G and are unable to complete an attended transfer. The process we are using is as follows:
- Answer incoming call on extension 1
- press transfer key
- press DSS key for extension 2
- extension 2 answers to speak to extension 1
- announce to extension 2 who is on the call
- extension 1 replaces the handset

After the handset has been replaced on extension 1 the call immediately recalls on extension 1, whilst on extension 2 the line is silent and the call timer continues as if its still on a call.

A blind transfer works fine

Any suggestions would be greatly appreciated.

Please help us to get the pcap and syslog and config.bin files. We can check something from them.

I know i'm bringing this post back from the dead... I am having the exact same issue with other model phones. Did you ever find a solution to this?

Sorry for the delayed response. Yes, this was resolved. The problem was our router configuration, to rectify the issue I disabled SIP ALG.
